| Outline of Final Research Achievements |
As a ‘comparative island study’, we conducted socio-economic surveys on livestock and tourism industry sectors for Ishigaki, Miyako and Yoron Islands in Japan and found that the structural features of the generation of environmental loads in each sector. We examined possible ways for controlling the environmental load generation based on the results of the surveys and a material flow analysis on the nitrogen from cattle farms. We made also various field measurements to clarify the propagation and material cycle processes of the environmental loads through surface and ground water flows and atmospheric precipitation. Moreover we developed computational models to quantitatively describe and predict the responses of coral reef and mangrove ecosystems under multiple environmental stresses.
